HTML Formatter & Minifier
Di HTML Formatter & Minifier
Our free online HTML Formatter & Minifier reformats messy or minified HTML with clean indentation for readability, or strips comments and whitespace to shrink file size for production.
A lightweight indent-based formatter/minifier for quick cleanup - not a full HTML rewriter, so unusual markup (inline SVG, conditional comments) may format imperfectly.
It's a lightweight, tokenizer-based tool built for everyday cleanup - paste your markup, format or minify it, and copy the result straight back into your project. Nothing is ever sent to a server.
Who Uses This Tool
Front-end developers use it to clean up HTML exported from a page builder or CMS before committing it to a repository. Web designers use it to make third-party embed code or a client's pasted snippet actually readable before editing it. SEO consultants use it during audits to quickly scan a page's markup structure for issues like missing tags or bloated nesting. Students learning HTML use the formatted output to study how a working page is actually structured. When file size matters more than readability, the minify mode strips comments and whitespace to trim a few extra kilobytes off a production page. Agency teams handing off a static build to a client also run it as a final pass, so the delivered markup looks deliberate and professional rather than machine-generated and cramped.

Frequently asked questions
Will this fix broken/invalid HTML?
No - it reformats indentation and whitespace, but doesn't validate or auto-repair malformed markup like unclosed tags. Use it for readability cleanup, not as a validator.
Is my HTML sent to a server?
No - formatting and minifying happen entirely in your browser; nothing is uploaded.
Does minifying remove HTML comments?
Yes - minify strips comments and collapses whitespace between tags to reduce file size for production use.
